The Renminbi's Dollar Peg at the Crossroads The Renminbi’s Dollar Peg at the Crossroads Maurice Obstfeld* University of California, Berkeley First draft: July 14, 2005 Revised: May 11, 2007 Abstract In the face of huge balance of payments surpluses and internal inflationary pressures, China has been in a classic conflict between internal and external balance under its dollar currency peg. Over the longer term, China’s large, modernizing, and diverse economy will need exchange rate flexibility and, eventually, convertibility with open capital markets. A feasible and attractive exit strategy from the essentially fixed RMB exchange rate would be a two-stage approach, consistent with the steps already taken since July 2005, but going beyond them. First, establish a limited trading band for the RMB relative to a basket of major trading partner currencies. Set the band so that it allows some initial revaluation of the RMB against the dollar, manage the basket rate within the band if necessary, and widen the band over time as domestic foreign exchange markets develop. The ultimate goal is a floating exchange rate coupled with some relative of inflation targeting. Second, put on hold ad hoc measures of financial account liberalization. They will be less helpful for relieving exchange rate pressures once the yuan/basket rate is allowed to move flexibly within a band, and they are best postponed until domestic foreign exchange markets develop further, the exchange rate is fully flexible, and the domestic financial system has been strengthened and placed fully on a market-oriented basis.

This paper was prepared under the auspices of the China Economic Research and Advisory Programme, sponsored by the East Asian Institute of the National University of Singapore. An earlier version of this pper was published in Chinese in He Fan and Zhang Bin, eds., In Search of an Internally and Externally Balanced Development Strategy: China and the Global Economy in the Coming Decade (Shanghai: Shanghai Finance and Economic University Press, 2006). From 1997 until July 21, 2005, the Chinese authorities pegged the renminbi (RMB) price of the United States dollar within a narrow range. On July 21, 2005, China’s authorities moved to an adjustable basket peg against the dollar, at the same time carrying out a 2.1 percent step revaluation of the central yuan/dollar rate relative to the prior central rate of 8.28 yuan per dollar. Figure 1 shows the course of the yuan/dollar nominal exchange rate over a longer historical perspective. Following a period of substantial cumulative inflation, the official rate of the RMB was devalued sharply in 1994, albeit in tandem with unification of the official and parallel exchange markets.1 A slight appreciation followed. Very notably in view of the claims that China’s exchange rate policy is dictated by the imperative of maintaining an undervalued currency, the authorities resisted substantial devaluation pressures, at the cost of some deflation, during the Asian crisis period starting in 1997. For some time now the situation has been reversed, with strong revaluation pressures, speculative capital inflows, and gathering inflationary momentum in the economy. The ability to resist speculative pressures comes from the maintenance of restrictions on private capital flows, especially inflows, as well as from administrative controls useful in restraining inflation.2 Nonetheless, “hot money” inflows and a burgeoning current account surplus have helped swell China’s foreign reserves immensely in recent years. Prior to July 21, 2005, most observers, and indeed the Chinese government itself, acknowledged that China’s exchange-rate arrangements were unsustainable and undesirable as a long-term foundation for responding, without disruptive episodes of inflation or deflation, to inevitable real-side shocks, as well as to secular changes in the 1 At the time of unification, the parallel rate already stood at a depreciated level relative to the official rate. 1 economy such as real appreciation due to Balassa-Samuelson effects. The July 2001 revaluation-cum-“flexation” is a response to the situation, including the external trade pressures it had generated, but leaves questions about how flexibility will be exploited in the future. So far, even the ±0.3 percent margins of yuan/dollar flexibility that exist have not been utilized fully.The rate of trend revaluation, although it has accelerated noticeably over time (see Figure 1), has been fairly small. Furthermore, capital markets that are open to the world seem a prerequisite for a modern high-income economy such as China seeks eventually to become. The issues concern the transition. How might China best move toward a genuinely more flexible exchange-rate regime? How might it best dismantle capital controls? And how might it optimally sequence these two conceptually distinct liberalization initiatives? These issues are closely interrelated, of course, and are central compenents of a more comprehensive program for rebalancing the Chinese economy, where consumption, especially of certain services, is too low, and investment, though high, is inefficient. More broadly, China’s financial development and rebalancing is critical for a smooth rebalancing of the global economy.3 In the following pages I have four goals. First, to provide a brief overview of developments in China’s real exchange rate, external accounts, and inflation, thereby filling in some concomitants of the nominal exchange rate trajectory in Figure 1. Second, to draw parallels with the experience of Germany (still an exporting powerhouse) during the Bretton Woods era. Third, to discuss the rather successful experiences of Chile and Israel in transiting from pegged exchange rates with capital controls to floating rates with financial opening. Fourth to draw some parallels with the experiences of Japan and 2 Prasad and Wei (2005) offer an excellent discussion. 3 On China, see Blanchard and Giavazzi (2005). On the global dimension, see Roubini (2007). 2 South Korea. Fifth and finally, to sketch a blueprint for gradually flexing the renminbi’s exchange rate in advance of capital-account liberalization.

Since 1994 the RMB has not depreciated over any significant time interval, and it was absolutely fixed in recent years until July 2005. The dollar has 3 fluctuated against other industrial-country currencies, however, and in China itself, inflation has been variable and, at times, high. The result has been substantial variability in the effective (or multilateral) real exchange rate of the RMB. Figure 2: CPI inflation rate 30.00 25.00 20.00 15.00 10.00 5.00 0.00 -5.00 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 Source: IMF, WEO database (April 2007). Figure for 2007 is an IMF staff forecast. Figure 2 shows the behavior of the CPI inflation rate for China since the late 1980s. Earlier spikes in inflation were associated with social unrest. Inflation was brought down after the mid-1990s, however, and, as noted earlier, even became negative during the late 1990s. Data for 2004 showed, however, a fairly sharp increase in inflation, to 3.9 per cent per annum. Annual inflation dropped to 1.8 percent for 2005 and 1.5 percent for 2006, but is forecast by the IMF to be 2.2 percent for 2007, surprisingly low given the underlying monetary landscape, but moving up relative to the PBOC’s presumed comfort 4 range. According to Monetary Policy Analysis Group of the People’s Bank of China (2007, figure 3), the year-on-year rates of increase in the CPI, consumer goods prices, and agricultural prices were all rather high in the final months of 2006. The dispersion of inflation across China’s regions is also sizable, compared to the situation in richer countries. The PBOC has raised interest rates several times in recent years. If the RMB is indeed undervalued relative to its long-run equilibrium position, as many economists and policymakers in China’s export markets claim, then the eventual approach to long-run equilibrium necessarily must involve some combination of domestic inflation (relative to foreign inflation rates) and nominal currency appreciation (relative to foreign currencies). If we assume a continuation of the cautious pace of nominal appreciation thus far, this perspective would suggest that an acceleration of domestic inflation is inevitable. Figure 3 shows China’s real effective CPI exchange rate index, as calculated by the IMF (with an increase being a real appreciation of the RMB). As inflation was brought down after the late 1980s, the currency depreciated in real terms, then appreciated in real terms, notwithstanding the 1994 nominal depreciation against the dollar, in the face of renewed domestic inflation. In the late 1990s the real external value of the RMB stabilized as the price level did. Most recently, the RMB has depreciated in real terms to somewhat below its Asian-crisis levels, in tandem with the dollar’s overall depreciation, with a very slight rebound evident after 2005.

  • Is the Chinese RMB Undervalued
    Department of Economics Uppsala University Bachelor’s Thesis Authors: Lars Barnekow and Martin Dalsenius Supervisor: Dr. Yngve Andersson Spring semester 2006 A Case Study of the Controversies of the Chinese Currency Regime 0 Abstract The debate on whether or not the Chinese currency is undervalued has been one of the most intensely debated economic subjects in recent times. The opinions amongst economists as well as politicians are all but homogenous. Through several different calculations, it has been estimated that the Chinese currency is undervalued, and should be appreciated, by as much as 30%. On the other hand there are several economists who think that this would cause severe damage to the Chinese economy with a clear risk of throwing it into a recession. Those who believe the latter either argue for no change from the present exchange rate policy until significant actions have been taken to sanitise the financial markets, or else that small liberalisations of the restrictions on capital flows are needed first. We make our own extensive examination of current theories and how they apply to the specific Chinese data. For instance data on China’s trade balance and the open market actions of the People’s Bank of China to maintain the exchange rate to the dollar while at the same time trying to keep its inflation goal. We also take a deep look at the Chinese domestic markets, the financial system, the possible effects on investment levels of abandoning capital restrictions etc. Eventually, we come to the conclusion that small gradual liberalisations of the restrictions on capital flows at the same time as the country takes serious measures to deal with its weak financial system is the best medicine for China.

  • The History of the Bank of Russia's Exchange Rate Policy
    The history of the Bank of Russia’s exchange rate policy Central Bank of the Russian Federation Abstract During the post-Soviet period of 1992–98, the monetary policy of the Bank of Russia was essentially exchange rate-oriented due to overall economic and financial instability combined with hyperinflation (1992–94) and high inflation (1995–98). An exchange rate corridor system was introduced in 1995. The government debt crisis of 1998 triggered a shift to a managed floating exchange rate. After that crisis, exchange rate dynamics were largely market-driven. The exchange rate continued to be tightly managed through 2002–05. In 2004, less restrictive capital control regulations were adopted, marking a move from an authorization-based system to flow controls. The rouble experienced steady upward pressure and the Bank of Russia intervened repeatedly in the foreign exchange market to contain the rouble’s appreciation. In 2005, the Bank of Russia introduced a dual-currency basket as the operational indicator for it exchange rate policy, again to smooth the volatility of the rouble’s exchange rate vis-à-vis other major currencies. Following the global financial crisis, the Bank of Russia changed its policy focus towards moderating the rouble’s depreciation. Interest rates were steadily raised, and a range of control measures was implemented. During 2009–12, the Bank of Russia further increased the flexibility of its exchange rate policy. Intervention volumes have steadily decreased. The overall scale of the exchange rate pass-through in the Russian economy has diminished in recent years. Greater flexibility on exchange rates has also let the Bank of Russia put increased emphasis on its interest rate policy.

Morrison Specialist in International Trade and Finance Foreign Affairs, Defense, and Trade Division Marc Labonte Specialist in Macroeconomics Government and Finance Division Congressional Research Service ˜ The Library of Congress China’s Currency: Economic Issues and Options for U.S. Trade Policy Summary The continued rise in the U.S.-China trade imbalance and complaints from U.S. manufacturing firms and workers over the competitive challenges posed by Chinese imports have led several Members to call for a more aggressive U.S. stance against certain Chinese trade policies they deem to be unfair. Among these is China’s refusal to adopt a floating exchange rate system. From 1994-July 2005, China pegged its currency (renminbi or yuan) to the U.S. dollar at about 8.28 yuan to the dollar. On July 21, 2005, China announced it would immediately appreciate its currency to the dollar by 2.1% (to 8.11 yuan per dollar) and link its currency to a basket of currencies (rather than just to the dollar). Many Members contend that the yuan has only appreciated slightly since these reforms were implemented and that it continues to “manipulate” its currency in order to give its firms an unfair trade advantage, which has led to U.S. job losses. Several bills have been introduced in Congress to address China’s currency policy, including S. 295, which would impose 27.5% in additional tariffs on imported Chinese goods unless it appreciated its currency to market levels.

    China’s Exchange Rate Regime: The Long and Short of It1 Barry Eichengreen University of California Berkeley March 23, 2006 1. Introduction China’s exchange rate system is a work in progress. The accelerating pace of change makes efforts to analyze it like attempting to hit a moving target. • In July 2005, following more than a year of intense discussion, the government announced that it was revaluing the renminbi by 2.1 per cent, switching from the dollar peg to a basket, and allowing the currency to float more freely.2 • In August it expanded the forward market by allowing all banks, including foreign banks, with licenses to trade in the interbank foreign exchange market to transact renminbi forward and swap contracts with clients as well as in the interbank market, and it allowed the banks to determine forward rates independently. The People’s Bank of China also provided additional information on the composition of the reference basket, specifying that it includes not just the dollar, the euro and the yen and the Korean won but also the Malaysian ringget, the Russian ruble, the Australian dollar, the Thai baht, the Canadian dollar and the British pound. The governor of the People’s Bank did not however reveal the weights on the constituent currencies. 1 Revision of a paper for Columbia University’s conference on Chinese money and finance held in New York on February 2-3, 2006. 2 The PBOC announced that it was keeping the existing fluctuation band that limits daily changes in the exchange rate to 0.3 per cent while allowing the operating range and thus the frequency and extent of repositioning of that band to depend more heavily on market conditions.

China’s Approach to Capital Flows Since 1978 Abstract Since China began its pro-market reform in 1978, its management of capital flows has followed a cautious learning-by-doing approach, guided by the goal of propelling strong economic growth while minimizing risk to stability. Claiming that the country’s financial infrastructure is still not ready to deal with large swings of financial flows, China has frequently fine-tuned restrictions of portfolio flows but generally kept a tight rein of those flows. Meanwhile, promoting foreign direct investment (FDI) inflows (and outflows in recent years)—with the aim of accessing foreign management know- how, technologies, raw material, and markets for exports—has been an important element of China’s development strategy. There is some evidence that China’s approach of encouraging FDI in strategic locations and sectors while restricting portfolio flows has contributed to its high growth rates since 1994.

  • 4- Traditional Central Bank Foreign Exchange
    - 4- I. INTRODUCTION Traditional central bank foreign exchange intervention occurs in spot currency markets. Likewise, the attention of researchers has focused on spot market interventions. However, the enormous growth in derivatives products has widened the array of instruments available to central banks to achieve their monetary policy goals. Some central banks are now investigating the potential uses of derivative products. The topic first received ( albeit limited) attention in the Hannoun Report (BIS, 1994), which considered the impact of recent financial innovation on the macro economy and monetary policy. More recently, there have been reports that several central banks have intervened in currency option markets. 2 This paper explores the opportunities and risks involved when central banks use the currency options market to achieve exchange rate stability in the foreign exchange market.3 The fact that monetary authorities intervene from time to time to achieve (often implicit) exchange rate target levels or to lower volatility in the foreign exchange markets has been established in the literature and is taken as given. The question considered here is whether and at what cost these objectives can also be achieved in the currency option markets.4 The contribution of this paper lies in analyzing possible central bank strategies in the currency option market and in showing that dynamic hedging by market makers need not always be destabilizing as commonly suggested in the literature.5 It is demonstrated that a strategy of central banks buying currency options (as advanced by Taylor (1995)) is flawed due to the destabilizing impact on the exchange rate of dynamic hedging by market makers, 2 For example, a press report credits the use of Hong Kong dollar put / US dollar call options by the Bank of China in 1998 as a contributing factor for keeping the Hong Kong dollar peg intact (Risk, April 1999).

The views expressed do not necessarily represent those of the Bank of Finland or the Union Bank of Finland. We are grateful to Jarmo Kontulainen and Carolina Sierimo for their help aI!d advice. ISBN 951::686-352-3 ISSN 0785-3572 Suomen Pankin monistuskeskus Helsinki 1992 ABSTRACT This paper examines developments in the Finnish money and foreign exchange markets in the light of the recent literature on target-zones. The basket-pegging system, which was officially adopted in Finland in late 1977, provides a good opportunity to discuss some of the implications of the target-zone models. Analysis concentrates on the period after 1987 when the assumptions underlying the basic target-zone model can assumed to be fulfilled. Although empiric~l exchange rate distributions of the Finnish markka do not seem to resemble those predicted by the basic target-zone model, the findings of the paper support the view that for a given period Finnish data exhibit some of the implications of target-zone models. The results, however, indicate that causality rons from the interest rate differential to the exchange rate and not from the exchange rate to the interest rate differential as implied by the basic (credible) target-zone model. 1n addition, intervention practices carried out by the central bank appear to have played an important role in determining the expected future exchange rate within the currency band.
